[en] Selective oxidation of Fe–3Al–6Cr alloy exposed to Zn/ZnO Rhines pack was conducted at 900 °C, 950 °C, and 1000 °C for 1–5 h. Results indicate that when the oxidation temperature reached or exceeded 950 °C, a complete external oxide film was obtained. Zn would vaporize and condense on the surface of the alloys. Zn uniformly distributed on the surface could dissolve in the α–Fe phase and Zn could be oxidized to ZnO and continue to react with the oxides of aluminum and chromium on the surface layer to form ZnM₂O₄ (M: Al + Cr) spinel. After selective oxidation for 1 h at 900 °C, Fe–3Al–6Cr alloy produced ZnM₂O₄ + M₂O₃ + α–Fe on the top surface and ZnM₂O₄, Al₂O_3, Fe₂Al₅, FeAl phases appeared on the subsurface. When the selective oxidation temperature reached 950 °C, a complete external oxide film was obtained, which completely covered the surface. ZnM₂O₄ + M₂O₃ oxides and α–Fe containing Zn appeared on the surface. External oxides ZnM₂O₄ and internal oxides of Al₂O₃ were found when Fe–3Al–6Cr alloy was oxidized at 1000 °C for 1 h. (paper)
